Fixed Disk Word

We kept getting requests, so we brought back the fixed-gear version of our Disk WORD hub. This unicorn enables the fixed-gear conversion of bikes with 135mm or 142mm rear spacing. It’s machined with care by us here in Chico, California. It’s absolutely bomb-proof, light, easily adjustable, serviceable, and comes with our own thick stainless steel lockring.

Product Story

We machine these hubs from 2-5/8″ round bars of aircraft grade 6061 aluminum. The hub shells are put through four different machining processes before they go to finishing, and the end result is something we’re very proud of. The flanges are canted towards the rim, and the spoke holes are chamfered to reduce stress on the head and elbow of the spoke.

The hub shell is available with dedicated fixed gear and lockring threading on one side, with a 6 bolt disc rotor mount on the other side. Proper left-handed lockring threading keeps fixed gear cogs secure, and our heavy-duty stainless steel lockring is included.

The axle is precision turned in-house from 7075 aluminum, which has a great strength to weight ratio.

We use high-fill sealed bearings, and they can be easily adjusted with our simple adjuster ring.

Our monthly email is an ongoing bike conversation for creative people who spend a lot of time in their garage.
Ever since we introduced our Quick Release Seatcol Ever since we introduced our Quick Release Seatcollar years ago, folks have been requesting a bolt-on version. But with so many other seatcollars on the market, we didn’t initially take the requests too seriously. Since the advent of dropper-posts, we started thinking about this more often. There really is a need these days for a seatcollar with deeper, more uniform clamping distribution: Enough to keep your dropper post from slipping in the frame, but also with a large, evenly dispersed clamping force to avoid the dreaded “dropper-binding”. The convex back of our “floating button” design evenly disperses clamping force, and avoids pinching or binding at a lighter weight than a steel barrel, is replaceable if damaged, and follows the simple PAUL aesthetic nicely. These are lovingly machined by us to the highest tolerances out of USA sourced 6061 & 7075 aluminum right here in sunny Chico, California. They are currently available in 30.0mm, 31.8mm, 33.1 and 35.0mm, in polished, purple, black, silver, and with orange accents. Available NOW on our website, or from your favorite local bike shop. If you want to learn more about it, search up our latest YouTube video. Have a great weekend, we hope you get to RIDE! ✌️
🚨New Shirt Alert!🚨 We’ve been offering this @the.s 🚨New Shirt Alert!🚨 We’ve been offering this @the.scorps T in classic black for a couple of years, and it’s definitely one of our favorites. But we felt like it was time to offer a more… shall we say… “Summer Dirtbag” appropriate version, and we think this Cloud Tie Dye version suits custom-cut-up-dirty-river-swimming-blackberry-picking-stains QUITE nicely. Available on our website right MEOW. ✌️
Lost and Found Gravel Festival, where do we even b Lost and Found Gravel Festival, where do we even begin?! We’ve been providing our world famous aid station for this event for yeeeears now, and it’s one of our favorite parties, I mean rides, of the summer! You can hammer this as a race, or register with a group of friends and take all day: you’re going to enjoy the scenery of the #LostSierra and the awesome vibes, no matter what. You’ll know you’re getting close to the PAUL aid station when you smell the bacon and hear the Grateful Dead (or Afroman😂). Also, all the money raised at this event goes right back into trail building and community in this area, so this is what pays off when you come back to ride Mt Hough, Mills Peak, Downieville, Lakes Basin, etc etc. June 13th is the date, register now and let’s party!

I know, it’s not that big of a deal, but it does c I know, it’s not that big of a deal, but it does come in handy and look real elegant. Our Klamper-inspired topcaps now come in a version with a built-in 5mm spacer. Some carbon fork manufacturers specify it, and sometimes you just wanna keep a touch of extra steerer tube around for adjustments or resale value. Anyways, The Rook is now live on the website! ♟️
We’re SUPER excited about this new trail network o We’re SUPER excited about this new trail network opening just up the mountain from us above Butte Meadows! Two trails are already finished, with 5 or 6 more in the works, and an eventual plan to connect this to the @sierratrails Connected Communities trails. Yeah, this is big! So… we asked @the.scorps if he’d be willing to donate artwork for a fundraiser T-Shirt, and he doodled up this fun drawing of the Colby Mountain Lookout. These are VERY limited edition, so if you want a sweet rare McNally shirt while raising money for a killer trail system in Lassen National Forest, head to our website quick before they’re gone! 📷: @explorebuttecountyca
